Converting PDF to Kindle Format AZW with Amazon Email

Amazon has a service for which they charge a nominal amount allowing you to convert documents such as .pdf (Adobe Acrobat Reader) files to Kindle files. To do this you must first have an active Kindle e-mail address. You can make sure you are set-up with a Kindle e-mail address by visiting the "Manage Your Kindle" section of the Amazon web site. Typically, your Kindle e-mail address will be "yourusername@free.kindle.com".

Step 1: Check to be sure the PDF file is not "protected." This can occur with e-books you have purchased with DRM (digital rights management) restrictions. You also might have documents that include passwords or other means to restrict access. You will not be able to convert these files.

Step 2: Create an e-mail to "yourusername@free.kindle.com" and attach the file you wish to read on your Kindle.

Step 3: When you get the e-mail back from Amazon you can transfer the document to your Kindle using the USB cable connected to your computer.

Pros:

Very easy, especially using the Whispernet option

Only requires an ability to send e-mail, so is cross-platform

Can batch convert multiple documents at once if sent in a .ZIP file

Free if returned to established Kindle e-mail address

Can handle non-embedded images

Cons:

Costs ten cents per document if returned via Whispernet

Little control of the returned document's formatting

Conversion of .PDF files is experimental, and the end result ranges from "pretty readable" to "yucky"
